I-Best Technology ingenye yabakhiqizi abahamba phambili be-pcb nabahlinzeki bebhodi lesifunda ephrintiwe e-China
Uma kukhulunywa ngokwenziwa kwamabhodi esekethe aphrintiwe (ama-PCB) nezinye izinto zikagesi, izindlela ezimbili ezivame ukusetshenziswa ama-laser stencil kanye nama-etching stencil. Nakuba womabili ama-stencil esebenza inhloso yokudala amaphethini anembile, izinqubo zawo zokukhiqiza kanye nezicelo zihluka kakhulu. Kulesi sihloko, sizochaza ukungafani phakathi kwama-laser stencil nama-etching stencil.
Iyini i-chemical etching stencil?
I-Chemical etching iyindlela yokukhiqiza ekhiphayo ehlanganisa ukusebenzisa ukwelashwa kwamakhemikhali ukuze ukhethe ngokukhetha okubalulekile kuma-substrates. Isetshenziswa kabanzi ekukhiqizeni amabhodi esekethe aphrintiwe (ama-PCB) futhi iphinde isetshenziselwe ukwenza ama-stencil. Inqubo yokubhala ama-stencil ngokuvamile ihilela ukufaka i-stencil ku-PCB, ukuhlanza kokubili i-stencil nebhodi, nokuphinda lezi zinyathelo kuze kube yilapho umphumela oyifunayo uzuzwa. Le nqubo ephindaphindayo ingadla isikhathi, iyenze ibe ngesinye sezici ezidinga kakhulu umsebenzi wokukhiqiza amabhodi akhethekile kagesi, ama-sub-assemblies, namabhodi esekethe. Ukuze banqobe izinselele ezihambisana nokuqoshwa kwendabuko, abanye abakhiqizi sebeqalile ukusebenzisa ama-stencil anqunywe nge-laser njengenye indlela.
Kungani usebenzise i-etching stencil?
Ama-stencil e-etching anezici ezilandelayo eziphawulekayo.
l Ukusebenza Kwezindleko:
Inqubo yokukhiqiza yokunamathisela ama-stencil ngokuvamile ifakazela ukuthi ibiza kakhulu uma iqhathaniswa nama-laser stencil.
l Ukunemba Okwanele:
Nakuba zingafinyeleli izinga elifanayo lokunemba njengama-laser stencil, ama-stencil aqoshiwe asanikeza ukunemba okwanelisayo kwezinhlelo zokusebenza ze-PCB ezihlukahlukene.
l Ukuvumelana nezimo:
Ama-stencil e-etching angashintshwa kalula noma alungiswe ukuze avumelane noshintsho lwesakhiwo, awenze afanelekele ngokukhethekile ukwenziwa kwe-prototyping kanye nokukhiqizwa kwezinga elincane.
Ama-stencil e-etching avame ukusetshenziswa ezinqubweni ze- through-hole technology (THT) futhi afaneleka kahle ezingxenyeni ezidinga idiphozithi ye-solder paste enkulu. Bathola ukufaneleka ezinhlelweni zokusebenza ezinokuminyana kwezingxenye eziphansi lapho ukuphumelela kwezindleko kuthatha okubaluleke kakhulu.
Iyini i-Laser stencil?
Ama-laser stencil, awaziwa nangokuthi ama-digital stencil, ayindlela yesimanje yokukhiqiza ekhiphayo esebenzisa ama-laser alawulwa ngekhompiyutha ukusika izinto ngokunembile zibe izimo namaphethini athile. Lobu buchwepheshe buvele emkhakheni wezokukhiqiza cishe ngo-2010-2012, okwenza bube busha embonini.
Naphezu kokuba yintuthuko yakamuva, ama-laser stencil anikeza izinzuzo ezimbalwa ngaphezu kwama-stencil amakhemikhali okufaka amakhemikhali. Abakhiqizi bangazuza ezidingweni ezincishisiwe zesikhathi nezinto ezibonakalayo lapho bedala ama-stencil besebenzisa le nqubo. Ngaphezu kwalokho, ama-stencil anqunywe nge-laser anikeza ukunemba okuthuthukisiwe uma kuqhathaniswa nozakwabo bamakhemikhali etching.
Izinzuzo zokusebenzisa i-laser stencil
Ama-stencil e-laser anezici ezilandelayo ezihlukanisayo.
l Ukunemba okuyisibonelo
Ukuqashwa kobuchwepheshe bokusika i-laser kwenza kudalwe amaphethini ayinkimbinkimbi futhi acwengisisiwe, okuqinisekisa ukunemba okukhulu ekufakweni kwe-solder paste kuma-PCB.
l Ukuguquguquka
Ama-Laser stencil anikeza ukwenza ngokwezifiso okungenamsebenzi kanye nezinketho zokuthunga ukuze kuhlangatshezwane nezidingo ezithile zedizayini, okuwenza afaneleke kakhulu uchungechunge olubanzi lwezinhlelo zokusebenza ze-PCB.
l Ukuqina
Lawa ma-stencil aklanywe kakhulu ngensimbi engagqwali ye-premium-grade, ewanikeza ukuqina okukhethekile nokuhlala isikhathi eside, ngaleyo ndlela evumela ukusetshenziswa okuningi.
Ama-Laser stencil athola ukusetshenziswa okubanzi ezinqubweni ze-surface mount technology (SMT), lapho ukunamathisela okunembayo kwe-solder kudlala indima ebalulekile. Ukusetshenziswa kwabo kuzuzisa kakhulu kuma-PCB anobukhulu obuphezulu, izakhi zephimbo elihle, kanye nokujikeleza okuyinkimbinkimbi.
Umehluko phakathi kwe-etching stencil ne-laser stencil
Umehluko phakathi kwama-laser stencil nama-etching stencil ungafingqwa ngale ndlela elandelayo:
1. Inqubo Yokukhiqiza:
Ama-stencil e-laser akhiqizwa ngokusikwa kwe-laser, kuyilapho ama-etching stencil enziwa aphumelele nge-chemical etching.
2. Ukunemba:
Ama-Laser stencil anikeza ukunemba okuphakeme, ubuncane bungu-0.01mm, buwenza alungele izingxenye ezizwakala kahle kanye nama-PCB anomthamo omkhulu. Ngokuphambene, ama-stencil e-etching aletha ukunemba okwanele kwezinhlelo zokusebenza ezinezidingo eziqinile.
3. Impahla Nokuqina:
Ama-Laser stencil akhiwe ngokuyinhloko ngensimbi engagqwali, eqinisekisa ukuqina kokusetshenziswa okuningi. Ngokuphambene, ama-etching stencil enziwa kakhulukazi ngethusi noma nge-nickel, okungenzeka awanalo izinga elifanayo lokuqina.
4. Izicelo:
Ama-Laser stencil ahamba phambili ezinqubweni ze-SMT ezibandakanya ukujikeleza okuyinkimbinkimbi, kuyilapho ama-stencil e-etching athola ukusetshenziswa okukhulu ezinqubweni ze-THT kanye nezinhlelo zokusebenza ezidinga amadiphozithi amakhulu ama-solder paste.
Ukukhetha phakathi kwama-laser stencil nama-etching stencil ekugcineni kuncike ezidingweni ezithile zenqubo yokukhiqiza ye-PCB. Amaphrojekthi adinga ukunemba okuphezulu, izingxenye zephimbo elihle, kanye nokujikeleza okuyinkimbinkimbi kungazuza ekusetshenzisweni kwama-laser stencil. Ngokuphambene, uma ukuphumelela kwezindleko, ukuguquguquka, kanye nokuhambisana namadiphozithi amakhulu okunamathisela kwe-solder kuthatha kuqala, ama-stencil okubhala anikeza isixazululo esisebenzayo.
